Title: Coordinate measuring device
Inventor: KANAI ATSUSHI
IPC: H01L21/30
Filed: 1992-07-03
Abstract: PURPOSE:To inhibit the deviation of a result of measurement due to the temperature of a sample, and to shorten the leaving time in a chamber before measurement in a coordinate measuring device measuring the accuracy of a photo-mask, the coordinates and line width of a reticle, etc. CONSTITUTION:A non-contact type temperature sensor 7 is installed on an objective 6, and the temperatures of a sample 2 are detected at every position of measurement. A function, in which the result of measurement is corrected by the temperatures of the sample 2 detected by the temperature sensor 7 at the time of measurement and the thermal expansion coefficient of the sample 2, is imparted. Consequently, the deviation of the result of measurement due to the temperatures of the sample 2 can be inhibited, thus improving the reliability of the result of measurement. Since measurement can be started regardless of the temperatures of the sample 2 at the time of measurement, the sample 2 need not be left as it is in a chamber 1 in order to conform a temperature in the chamber 1 and the temperatures of the sample 2, thus largely shortening the time.

Filed: 1994-07-28
Abstract: PURPOSE:To make it possible to align a focal position at all times without depending on the distance from an image pickup plane of an image pickup means by arranging this image pickup plane by inclining the image pickup plane in a direction perpendicular to the optical axis at the time of image pickup. CONSTITUTION:A lens 3 is mounted at the front end of a scope and the light from a subject collected by this lens 3 is received by a CCD 5 as the image pickup means mounted with inclination with the direction perpendicular to the optical axis of the lens via a filter 12. This CCD 5 converts the received light signal to an electric signal which is transmitted via a CCD flexible cable 6 and a CCD cable 7 to a console where the image is formed. The focus of the subject is surely matched if the front end of the scope is delicately adjusted without depending on the distance from the front end of the scope up to the subject. The observation of the subject is, therefore, possible in the state of focusing the subject at all times even if bringing of the front end of the scope near to the subject is not possible or even when moving of the front end apart therefrom is not possible. The diagnostic performance is markedly improved.

Abstract: PURPOSE:To obtain a stable and high precision, by adding such compensating signal to the input of a servo amplifier that an initial torque is cancelled. CONSTITUTION:When a ship body 1 is oscillated, the initial torque due to eccentricity of the center of gravity is applied to a radar antenna 2. The rocking angular velocity of the ship body 1 is detected by a rate gyro 10, and the output becomes the same waveform as the rocking of the shop body 1. This output is inputted to a differentiator 11 and is differentiated, and a similar waveform having a polarity opposite to that of the initial torque is outputted from the differentiator 11. The output of the differentiator 11 is added to the output of an operator 6 in an adder 12 to become a current command 7. A current corresponding to this command 7 is supplied to a motor 9 by a servo amplifier 8, and a driving torque corresponding to the current is generated by the motor 9 and is applied to the antenna 2. This driving torque has a waveform similar to the command 7. Consequently, the driving torque cancels the initial torque, and the antenna 2 is not moved.
